The definitions of performance criteria are as follows:
• Performance criterion A — During test normal performance within the specification limits
• Performance criterion B — During test, temporary degradation, or loss of function or performance
which is self-recovering
• Performance criterion C — During test, temporary degradation, or loss of function or performance
which requires operator intervention or system reset occurs.
